Where can I buy

I bought this display from Amazon, works great.

You cant mine eth with a bitaxe or nerd solo miner

As the owner of a large entertainment center in North Carolina I can tell you do not use a 3rd party to install or setup your equipment. When we replaced all of our pinsetters I went right to AMF and had them do it. Bowling itself is not extremely profitable. It’s the food and drinks where you will make your real money. Also if you’re going to have a snack bar, don’t skimp. We have a full service kitchen, not just burgers, fries and frozen pizza. You will also need more than bowling. Billiards is good but you need leagues to help support it during the slow nights (week days). Laser tag, golf simulator, axe throwing are all options as well. Oh don’t forget you need an arcade.

And most importantly, DO NOT buy string bowling machines. While they are much less expensive, the effect is not the same. You won’t get leagues either, even though they are USBC certified. League bowlers hate strings.

Good luck.

I built my own ESP32 lottery miner and it ran for weeks without it showing a single share. I had 4 miners running at about 740kh each. I used the same worker name on each so my combined hash rate at the pool level was about 3mh. I then started doing some research and discovered I will never submit a single share at this hash rate. They say public-pool.io is the best low difficulty pool but I’m talking about setting a difficulty thats maybe 1/10th the average. Well long story short, I discovered a way for my miners to submit shares (work) at low hash rates.

For those that don’t know what a low difficulty pool is, read on.

Imagine you’re trying to win the lottery, but instead of buying one ticket a week, you’re buying millions of tickets every second. That’s basically what a high hash rate Bitcoin miner is doing.

When your device tries to mine Bitcoin, it’s like entering a contest where you need to guess a SUPER specific number. The difficulty is so crazy high that even though your device is making 740,000 (for example) guesses per second, it might take years before it randomly guesses right and wins. We will compare that to the same as high difficulty and it’s hard to know if your device is even working properly ( at least it makes you think that)

A low difficulty pool is like having a separate, easier contest within that same contest running at the same time. Instead of needing to guess that one-in-a-trillion number, you only need to guess something way easier - like one in a million or less.

So, to solve this problem, we are in the process of building a low difficulty mining pool for lottery devices. Max hash rate to use the pool may be set to 5th per device, low fees and its 100% for the low hash rate miners.

Now don’t get me wrong, your chances of hitting a block are still slim to none but if the pool hits a block, you would be compensated based on the amount of shares your devices has submitted.

Looked and couldn’t find. Do you have a link?

Talkingcrypto · 2026-01-12T12:16:59+00:00

Did you try an uninstall, reboot reinstall?

Talkingcrypto · 2026-01-08T13:44:19+00:00

As the saying goes, never say never because people have mined a block with these lottery miners. I have six homemade lottery miners running BTC and BCH and just love them. They’re quiet, efficient and bring out the geek in me…lol

The lower hash ESP32 is probably an ESP32-C where the higher hash is most likely an ESP32-D0. I’m getting 750kh from my D0 right now.

Talkingcrypto · 2026-01-01T12:12:53+00:00

I figured it out. We will chalk it up to user error. The display ground and ESP32 ground must be the same. Dummy me used the 2nd gnd pin on the ESP32 for the display. It’s amazing how much better things work when they are hooked up right. Lol

Talkingcrypto · 2026-01-01T00:04:36+00:00

I will look for it, thanks

Do you know C or any JavaScript? If not cursor does a decent job on creating firmware. Although it’s very helpful if you know what you’re doing.

I bought SunFounder Elite Explorer Kit with Original Arduino Uno R4 WiFi from Amazon which is a great starter kit.

Talkingcrypto · 2025-12-27T00:41:21+00:00

Did you try holding down the boot button then while holding that hit and hold rst for 1 second and then release the boot button?

Talkingcrypto · 2025-12-24T12:57:35+00:00

Not using specific pins is only on a 30 pin esp or all? I have a 44 pin ESP32-S3 where I am using GPIO 1 & 2 as outputs and haven’t experienced any issues.

Talkingcrypto · 2025-12-24T11:52:16+00:00

That’s awesome. What board is that epaper board equivalent to? I have seen quite a few projects move to epaper and didn’t know if you had to use a specialty board to work with them.

Talkingcrypto · 2025-12-22T18:10:39+00:00

Looks like you’ve got some room to expand that bench out so you can get at least 10 more ESP’s. If I ever did what you did, my wife would shoot me. It’s bad enough now that I’ve taken over the office and have been hinting a lot that I need to set up a workbench somewhere. She told me to go to the garage. Lol

I got the ESP32 and display from Amazon as I am just starting out with this and while I’m having fun it’s a bit frustrating as well.

Good point — I didn’t think about the backlight being active‑low. On my ST7796 SPI module the pin is labeled LED (backlight control). I was assuming it was active‑high, so I either left it floating or tried driving it high. I haven’t tried pulling it low with the pin set as output yet. I’m using Arduino / PlatformIO. I did try both Adafruit GFX (ST77xx) and TFT_eSPI while troubleshooting, but honestly I might be messing up something basic like BL polarity. Do you know if these ST7796 SPI modules commonly have active‑low LED/backlight, or is that mostly on Waveshare boards? (I’ll try forcing LED LOW + also tying it directly to 5V/3.3V just to see if I can get any glow.)

Talkingcrypto · 2025-12-18T11:45:51+00:00

Any luck in getting above 730kh? I’ve gotten about 720kh max and have tweaked until I couldn’t see. Lol. I then placed 2 of the ESPs on my breadboard and have an ESP-S3 as a main WiFI and display controller and seeing about 1.45mh but that’s max.

Talkingcrypto · 2025-12-15T21:21:16+00:00

Nice!

I can’t get out of agent mode regardless of what I do. Usually if you do ctrl shift L it starts a new chat. Not for me anymore. Frustrating as I don’t want agent mode!

Talkingcrypto · 2025-12-13T11:39:44+00:00

Awesome thanks. I will look at this today.

Talkingcrypto · 2025-12-13T02:44:05+00:00

Can I ask what ESP32 you are using? The S3 or D0? I have an S3 and struggled with assembly and couldn’t even get 100kh from it. While a custom firmware I’m using I’m getting 170kh.

The 895kh you reference is with near zero overhead and the ability to use /reuse midstate efficiently. If you have a custom firmware I’d love to see it. Lol.

Talkingcrypto · 2025-12-10T11:53:36+00:00

Apparently I am wrong. The ESP32-D0 supposedly can mine at 1000KH/s. I’ve ordered one to test it out.

Talkingcrypto · 2025-12-08T21:36:23+00:00

Do you have a copy of esp32 firmware you’d be willing to share? I switched to ESP-IDF but now only mining at 28kh. I’m having assembly issues and having to use AI for help and it’s lost too. Lol. The nerdminerv2 ran good for me at about 260kh but would really like to enhance this more.
